Hermetic TO-99 op-amp for legacy and sealed-envelope designs
The hermetic metal can package suits applications where moisture resistance, long-term reliability, or retrofit compatibility with existing TO-99 footprints matter — avionics instrumentation, test equipment, and sealed sensor modules. Input bias current is 30 nA typical, input offset voltage 3 mV typical.
The 10 V to 44 V supply span covers standard ±5 V to ±15 V bipolar rails and also single-supply operation up to 44 V, giving flexibility in existing ±15 V instrument designs or 24 V industrial control loops. For extended-temperature or automotive use, a different op-amp family with industrial or military rating would be needed.
This is relevant for sustaining legacy designs that depend on the TO-99 package and through-hole assembly — no forced redesign due to obsolescence.
